Unique speed-cut design allows for smooth draw and easy re-holster without slowing you down. BlackHawk CQC™ (Close Quarters Concealment) holsters and accessories SERPA Technologyis a simple-to-use active retention system that automatically locks the weapon as you holster it. To release, just press the lock device on the outside of holster with your trigger finger. The unlocking device is positioned right where your finger naturally rests. There is no awkward middle finger release or thumb break to slow you down.

This is the best concealment holster I have ever used, no more holding your weapon so it won't fall out and the safety feature is the best click and it's secured, my buddy has a glock too and when he saw mine he bought one the next day.
